Disclosed is an elastic body with an adjustable hardness and height, comprising an upper elastic body (1) and a lower telescopic body, wherein the elastic body (1) comprises at least one elastic unit (2) arranged longitudinally and transversely; the elastic unit (2) is fitted around a bag-like structure (3), or a traction mechanism is directly arranged at the upper end of the elastic unit (2); the telescopic body is formed by a base (4) and a movable support (5) arranged on the base (4); the lower end of the elastic unit (2) is fixed to the movable support (5); a pull rope (6) is fixed to the bag-like structure (3) or the traction mechanism; a plurality of elastic units (2) share one pull rope (6), or one elastic unit (2) uses a plurality of pull ropes (6) or one elastic unit (2) uses one pull rope (6); the pull rope (6) passes through the elastic unit (2) along the axis of the elastic unit (2) or the pull rope (6) passes through a gap between the elastic units (2), or a plurality of pull ropes (6) pass through the interior or the vicinity of the elastic body (1) and continue to pass through the movable support (5) to be connected to the base (4); and the movable support (5) moves up and down to drive the bottom part of the elastic unit (2) to compress or loosen the elastic unit (2) so as to adjust the hardness and/or height of the elastic body (1). The elastic body with an adjustable hardness and height is applied to pillows, cushions, soft cushions, sofas, back cushions and mattresses, so as to achieve the adjustability of hardness and/or height. |
